テーブルスキーマに対して実行できるクエリの結果と同じカラム情報にアクセスできます。返されるカラムについては、カラム を参照してください。

結果セットメタデータの取得

WorkdayDataReader のGetSchemaTable メソッドを使用して、結果セットのメタデータを取得できます。GetSchemaTable は、ExecuteReader を呼び出してから呼び出します。

DataTable の各行は、クエリの結果のカラムを説明します。

C#

string connectionString = "ConnectionType=SOAP;User=myuser;Password=mypassword;Tenant=mycompany;BaseURL=https://wd3-impl-services1.workday.com";

using (WorkdayConnection conn = new WorkdayConnection(connectionString)) {
  WorkdayCommand cmd = new WorkdayCommand("SELECT * FROM [CData].[Human_Resources].Workers WHERE Legal_Name_Last_Name = 'Morgan'", conn);
  WorkdayDataReader rdr = cmd.ExecuteReader();
  DataTable schemaTable = rdr.GetSchemaTable();
  foreach (DataRow row in schemaTable.Rows) {
    foreach (DataColumn col in schemaTable.Columns) {
      Console.WriteLine("{0}: {1}", col.ColumnName, row[col]);
    }
  }
}

VB.NET

Dim connectionString As String = "ConnectionType=SOAP;User=myuser;Password=mypassword;Tenant=mycompany;BaseURL=https://wd3-impl-services1.workday.com"

Using conn As New WorkdayConnection(connectionString)
  Dim cmd As New WorkdayCommand("SELECT * FROM [CData].[Human_Resources].Workers WHERE Legal_Name_Last_Name = 'Morgan'", conn)
  Dim rdr As WorkdayDataReader = cmd.ExecuteReader()
  Dim schemaTable As DataTable = rdr.GetSchemaTable()
  For Each row As DataRow In schemaTable.Rows
    For Each col As DataColumn In schemaTable.Columns
      Console.WriteLine("{0}: {1}", col.ColumnName, row(col))
    Next
  Next
End Using
